Geeks: We've Got Your Number
Regular numbers? Those are for amateurs. Bring your inner genius out for all to envy with a smart and stylish watch that features the equivalent notation of each number.
For nascent mathematicians and victims of the occasional memory lapse, a cheat sheet is included with each watch.:
1: i is equal to the square root of -1, so i^2= -1. The absolute value of -1 is 1.
2: This represents 2 in binary code.
3: The cube root of 27
4: 11 base 3, which represents 4 in the ternary system
5: Log(20x)=2 is equivalent to 20x=10^2 or 20x=100, where x=5.
6: Euler's product formula: phi(p^k)=(p^k)(1-(1/p)), where (p^k)=9
7: This is a binomial coefficient, so with the formula n/k = (n!)/((k!)(n-k)!), n/k=7.
8: This is a natural logarithm where ln(e^x)=x, so ln(e^8)=8.
9: This summation is equal to 3(1)+3(2)=3+6=9.
10: Since clocks "wrap around" every 12 hours, the hour number starts over after it reaches 12. This is arithmetic modulo 12. 10mod12 is 10:00, and 16mod12 would be 4:00, for example.
11: B'L is Legendre's constant, which is equal to 1, so this equation becomes the square root of 121, which is 11.
12: Hexadecimal representation of 12
